Utilization of addi-

tional technology

In some cases, a simple extraction and filter system isn’t
enough. For example, when dealing with moist laser dust
from plastics or organic materials like paper or wood, a
filter aid is almost always necessary. This helps improve
the separation of particles and significantly extends filter
life. FILTER AID FOR

Additionally, laser processes often produce odors or gas-
es that can be removed using adsorption methods (like
activated carbon or chemisorption).
